INSULATING CLAMP med July 9. 192s Patentedv Aug. 11, 1931 UNITED STATES CHARLES r 1a..'roIINS'oN, or CHICAGO, ILLINOIS "INSULATING cLAMr Appii'eati'oaled Juiya, 192s.: 'serial No. 291,31'2.` l

VMy invention relates tov insulating clamps and the like and las a specific form of application consists of a thin plate-like structure whichisof use in connection Xvith'apparatus designed for the purpose of permanently Wavinghuman hair. This plate-like structure consists of a pair of movable elements so that an indeiinite amount of hair may be clamped between the movable sections, the

l0 plate-like structure itself resting against the head so as to form an insulating 'barrierto prevent heat from the heaters Which are utilized in the curlinor operation from 'affect-H n through the three plates 10,111 and 14. The

ing the scalp.

In one of its forms, the structure is also designed so that it may clamp the hair suliiciently tight so that moisture from the heaters is prevented from reaching the scalp.

My invention has a plurality of uses but i I Will describev the specific form above indicated more in detail by referring to the accompanying drawings in Which- Fig. 1 is a plan view of a clamp constructed J in accordance With my invention;

' 2b Fig. 2 is a similar vieW showing the parts in their alternative position;

Fig. 3 is a similar view showing the device clamping a bundle of hair;

Fig. 4 is a sectional View on line v4--4 of Fig. 5 Showing the parts in their retracted position; and l Fig. 5 isa sectional view on line 5-5 oli' Fig. 4.

In the `form shown, my device consists of two thin plateslike element-s 10, 11, these elements 10 and l1 having finger holds 12 and 13 respectively. These two plates are held in relatively fixed relationship and carry between them a third plate-like element14 shown more clearly in Fig. 4. The elementsV 10 and 11 are heldintheir fixed relationship by the bolts or rivets or other'suitable fastening means 15, 16 and a third fastening element 17 holds all three elements A10, 11 and 14 in'pivotal relationship.

A spring 27 iinding a support upon the fastoningl means 15 has its free extremity 18 urging the element 14 in a countercloclrwise direction (see Fig. 4). The other free extremity ventiOn.

Vplate-like superposed clementsfhaving aligned 19ofthe spring is anchored in the plate 10 for purposes that are obvious.

The plates 10 andl 11 are provided with a suitableslct 2O WhicheXtends radially from theperiphery to the center of these plates V where this slot is preferably enlarged to form a more or less circular hole. The slots 20 and holes 21 inthe two plates 10 and 11 are superposed as shown. The element 14 has-atjits intermediate portion a rounded cutawayv section 22 so that when this element risfin `its retracted position as shown in Fig. 4 the hole 21 'constitutes an unobstructed opening element 14 is providedwith a finger hold 23 65 as shown. In using lthe device as shown in F ig. 1, the finger vholds 12,v 13 and 23 are grasped and the device opened-into theposition as shown in Fig. 2j The desired quantityof hair may'then he introduced through the slot 20 into theh'ole 21and the pressure ron thelingerv holds is 'released so that the spring 27 may forcethe device so that its respective elementsV occupy the positions shown f kin Fig. 3 With thebundle of hair 24 clamped 75 Vtightly-togetherl A l It Will beapparent that the circumferen- *n tial-portion 25 .of the `element 141s then'in position to entirely close the slot'20 and also Vthe hole 21 With'the 'exception'of that por-*80 tion occupied by the hair. The clamp when in position' upon the scalp rests snugly against the scalpandit is a'prime'desideratum of a device of this kind that it beeXtre/melythin 1 yso that the hair may-be waved or curledto a- 8b point as close tothe scalp as possible. The

edge of they material-about thehole 21 may be corrugated if` desired" i From what has been thus described, the

naturevof my invention Will.` be readily clear" ktri-those skilledin the art and it .Will also be apparent that modifications :may be vmade Without kdeparting fromfthe spirit of my in` What I claim as new and desire to secureg: by Letters :Patent is: 'f

- 1. A clamp' of thecharacterrand for the i` u purposes speciied comprising a pair'of spaced radial slots, anda third plate-like element.

swinginglyy mounted between said iiist aforesaid elements and adapted in one limiting position to open said slots and in its other limiting position to close said slots, said elements having means to olanip unlike portions of material interiorly of their periphery and simultaneously to close the unoccupied portion of said slots, said third element being cut away at one side whereby to leave an open space between said pair of elements adjacent the material beingclaniped to'permit free access of air to the clamped material.

2. A hair clamp for hair waving comprising a pair of spaced thin heat insulating diskshaving aligned slots extending inwarr 1y from their peripheral. edges, said slots being enlarged at their inner ends7 and a plateflike element swingingly mounted between said disks movable across said slots to `elamp hair in the inner ends thereof, said `yelement leaving the space between said disks `opposite its advancing edge substantially unobstructed to permit air circulation between said` disks adjacent the hair therein for cooling the same.
